New and Remanufactured Mazda Miata Ignition Control Modules

Ignition control modules work by monitoring a host of information provided by sensors around the vehicle and
then firing the ignition coil / spark plugs at the right time. Many also maintain the proper air / fuel ratio
by keeping fuel injectors open for the appropriate amount of time.

Ignition control modules, as with any electronic component, can fail and require replacing. When an ignition
control module fails, the engine will usually begin missing due to plugs not firing when they should. This will
lower fuel economy, reduce performance and could cause damage to the exhaust system from unburnt fuel. Diagnosing
an ignition control module can be done using a multi-meter if you're familiar with the proceedure. Otherwise
it should be handled by an automotive professional.

Replacing ignition control modules will vary in difficulty depending on the vehicle and the module's location. Always
consult a certified automotive professional if you are unsure of the proceedure.
